Floods

The UK is struggling to deal with the most serious flooding in living memory; the other week it was South and East Yorkshire suffering, now it is Shropshire, Worcestershire, Gloucestershire, and Oxfordshire. Thousands of homes are under water, and ironically many of them are without water to drink because a water treatment plant has also gone under. The submersion of an electricity sub-station has compounded the misery for those who now find themselves without either water or power. The rivers Severn and Thames are still rising, with the worst to come, and many people near or in Oxford have been evacuated to a sports stadium. South-west London is said to be the next in line, as the Thames continues to rise. More heavy rain is forecast for the London area, exacerbating the situation, and this is set to combine with high tides.

All this coincides with a government announcement that they will still be going ahead with the planned development of hundreds of thousands of new homes in the south east to meet demand, many of which will be build in known flood plains. Of course it is now stated that building will only take place if proper flood defences and adequate drainage can be put in place.

Surely one solution when building in such areas would be to build higher footings, i.e., up to the damp course, say about 3 or 4 feet higher than is current practice. Why do our houses have to sit at ground level? Is this such an obvious and simple solution that nobody will put it into practice? Probably.

UK Floods

The horrific flooding experienced this week in South Yorkshire, the Midlands, and other parts of Britain has been described by some as an "Act of God". It is no such thing. It is an Act of Man.

For decades we encouraged farmers (with financial grants and subsidies) to rip out hedgerows to make bigger fields, and to put in subsoil land drainage systems.

Result? Faster rainwater run-off.

At the same time the River Boards of the 1960s and 1970s went on a mad spree of environmental destruction in the interests of Land Drainage, turning meandering river systems into straight, vegetation-free, drainage canals resembling aquatic motorways.

Result? Faster movement of flood water from A to B.

Whilst all this agricultrual mayhem was going on, town and country planners were merrily permitting housing and industrial development in flood plains, against the advice (in earlier days) of the same River Boards that were destroying the rivers' natural ability to balance the discharge of flood waters, and against the advice (in more recent times) of the Environment Agency.

In the older suburbs of our major towns and cities that were built before the age of mass car ownership you will also find people rooting up their front gardens and converting them into paved areas to accommodate one, two, or sometimes three cars.

Result? Additional surface water run-off to overload inadequate storm drainage systems.

At last, though somewhat too late I fear, farmers are considering the re-planting of hedgerows, and the Environment Agency talks about the desirability of allowing agricultural grassland to be given over to floodwater balancing. More voices are being raised by politicians and others about the need to take seriously the matter of building houses, factories and offices in areas known to be prone to flooding.

We have only ourselves to blame for many of our so-called environmental disasters.
